NAIL-PULLING IMPLEMENT.

Specification of Letters Patent.

Patented Au. "2?, 1917.

Application filed December 30, 1916. Serial No. 139,923.

To all whom it may concern:

Be it known that I, ANGUS MOLEOD, a subject of the King of Great Britain, residing at Fairville, Province of New Brunswick, Dominion of Canada, have invented certain new and useful Improvements in Nail-Pulling Implements, of which the following is a specification.

This invention relates to implements employed for pulling nails and for like purposes, and has for one of its objects to provide a device which may be engaged with the head of a nail and employed in coaction wit? a pulling implement to withdraw the nai Another object of the invention is to provide a device of this character associated with a nail setting attachment.

WVith these and other objects in view, the invention consists in certain novel features of construction, as hereinafter shown and described and then specifically pointed out in the claims; and in the drawings illustrative of the preferred embodiment of the invention Figure 1 is a perspective view of the improved implement.

Fig. 2 is a perspective view of a nail located in position to be engaged by the implement.

Fig. 3 is an edge view of the lower or nail engaging portion of the implement.

Fig. 4 is a view of the implement partly engaged with the head of a nail.

Fig. 5 is a view of the implement fully engaged with the head of the nail and with a pulling instrument, such as a claw hammer, engaged with the implement, to illustrate the operation of withdrawing the nail.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

Nails are generally driven their full lengths into the structures in which they are employed and then set by a suitable implement still farther into the structure un-- til the heads of the nails are disposed for a considerable distance below the outer surface. The removal of the nails is thus rendered very difficult and'is generally accomplished by knocking the parts of the structure loose, resulting frequently in their destruction. To remove the nails without battering or disfiguring the structure in which divided by a longitudinal cleft into coacting portions 12-13. The stock is formed of tempered steel so that the members 12-13 are resilient and normally engaged face to face, as illustrated in Fig. 1. At their lower ends the members 1213 are reduced and formed with flat relatively thin webs 14r15, the webs being pointed, as shown at 1617, at their lower ends. The webs eX- tend for a considerable distance below the lower ends of the portions 12-13, and the latter terminate in lateral shoulders 18-19.

Formed in the confronting faces of the webs 14:'l5 are recesses 21-22. Projecting from the head portion 11 of the stock is a nail set member 23. The members 12-13 are preferably offset laterally, as illustrated at 24 to facilitate the engagement of the pulling implement therewith, as hereafter explained.

The body of a nail is represented at 26 and the head at 27.

With an implement thus described the operation is as follows:

The points 16-17 are disposed at opposite sides of the head 27 of the nail which is to be withdrawn and the implement driven into the material adjacent to the nail by the blows of a hammer or like implement applied to the head 11. The curved inner edges of the points 1617 engage the opposite edges of the head 27 of the nail as the implement is driven into the material and the parts 1213 are thereby forced. apart and caused to assume the position shown in Fig. 4. The blows of the hammer being continued the lower edges of the recesses 2122 pass below the lower edge of the head of the nail and the resiliency of the members 1213 causes them to move toward each other, or assume the position shown in Fig. 5, with the head of the nail within the recesses 2122.

A suitable pulling implement, for instance the claws 28 of a hammer, are passed upon each side of the projecting portion of the webs 1l-15 and beneath the shoulders 1819. Then by actuating the handle 29 of the hammer the implement is moved upwardly and carrying the nail with it, as will be obvious. If the nail is rusted in the material into which it has been driven and adheres thereto, a few blows of the hammer upon the head 11 of the implement will cause the upper ends of the recesses 21 22 to engage the outer face of the nail head and drive the nail farther into the material, thus loosening the nail and enabling it to be easily withdrawn when the pulling implement is applied.

The offset portions 24 of the members 12-13 permit the handle 29 of the hammer to be disposed in the position shown in Fig. 5, when in its initial position.

The improved implement is simple in construction, can be inexpensively manufactured and will be found very useful for mechanics in Withdrawing nails from structures which are to be repaired or dismembered, and will likewise be found very convenient in Withdrawing nails from the closures of shipping cases and the like.

The nail set feature 23 may also be employed to loosen the nail when the latter is rusted in the material instead of loosening the nail by driving the implement farther therein, as previously described, in addition to its use in an ordinary nail set.

Having thus described the invention, what is claimed as new is- 1. An implement of the class described including coacting resilient members having nail head receiving recesses in their confronting faces, the material of the members diverging in advance of the recesses to cause the separation of the members when forced longitudinally of the nail.

2. An implement 0f the class described including coacting resilient members having lateral shoulders adapted to be engaged by a pulling implement and with nail head receiving recesses in their confronting faces, the material of the members diverging in advance of the recesses to cause the separation of the members when forced longitudinally of the nail.

3. An implement of the class described,

comprising a stock formed with coacting resilient members having lateral shoulders and reduced in advance of the shoulders, said reduced portions having nail head receiving recesses with the material in advance of the recesses diverging to cause the separation of the members when the implement is forced longitudinally of the nail.

4:. An implement of the class described, comprising a stock formed with coacting resilient members and laterally offset near one end and reduced in advance of the off-set portion, said reduced portions being pointed and provided with nail head receiving recesses in their confronting faces, and said stock adapted to be engaged by a pulling instrument.

5. An implement of the class described, comprising a stock having a dividing cleft extending for the major portion of its length to form coacting resilient members engaging normally face to face, said members being pointed at one end and with nail head receiving recesses in each member, said stock adapted to be forcibly moved longitudinally to withdraw a nail.

6. An implement of the class described, comprising a stock having a dividing cleft extending for the or portion of its length to form coacting resilient members engaging normally face to face, said members being pointed at one end and with nail head receiving recesses in each member, and a nail setting projection on the uncleft por tion of the stock.

7. An implement of the class described, comprising a stock including coacting resilient members with lateral shoulders and relatively thin webs in advance of the shoulders, said webs being pointed and with nail receiving recesses in their confronting edges, the material of the webs in advance of the recesses diverging to cause the separation of the members when forced longitudinally of the nail.

In testimony whereof I affix my signature.
